Memory debugging with Totalview 8

This article explains how to manage Totalview 8 and greater for debugging the memory corruption and track the memory leaks.

We have the possibility to debug the memory access with the new Totalview 8.

The latest documentation for totalview is available here.

SEP2 offers the possibility to manage the linking by setting the environment variable $TV_HOME

For OSF1

setenv TV_HOME /soft/totalview/toolworks/totalview.8.x.y-z

The compilation flag is : TV then to build your application: make DEBUG=1 TV=1

The consequences are :

cxx  -DCORBA_VB3_3 -pthread -call_shared ... -L/soft/totalview/toolworks/totalview.8.0.1-0/alpha/lib ... -lElapsed_d -lorb_r  -lname_r    -ltvheap ... myApplication_d

Lets run your application normaly : totalview myApplication_d -a -cfgName ../myConfigFile

For AIX

Be careful : your machine must be at least in AIX 5.3 ML5. To verify the machine, please enter : oslevel -r. The last digit is the level. By example  5300-03 means ML3 and 5300-05 means ML5.

setenv TV_HOME /usr/totalview

The compilation flag is : TV then to build your application: make DEBUG=1 TV=1

The consequences are :

xlC_r  -I. ... /soft/toolworks/totalview.8.2.0-0/rs6000/lib/tvheap.a -o ./myApplicationApp_d ... 
-L/soft/toolworks/totalview.8.2.0-0/rs6000/lib ...

Add the following environment variables :

setenv AIXTHREAD_MNRATIO 1:1
setenv AIXTHREAD_SLPRATIO 1:1
setenv AIXTHREAD_SCOPE S

Lets run your application normaly : totalview myApplication_d -a -cfgName ../myConfigFile
